car·box·yl

(kar-bok'sil),
The characterizing group (-COOH) of certain organic acids, for example, HCOOH (formic acid), CH3COOH (acetic acid), CH3CH(NH2)COOH (alanine). Compare: carboxylic acid.

Based on the solution P concentrations, it appears that benzoic and cinnamic acids behave as distinct groups, with the key differences in their structures being the distance of the carboxyl group from the benzene ring and the inclusion of a double-bond in the carboxyl side chain, both of which may influence their ability to form stable complexes with P in solution.
